Okay, I've made a great game, that I think would be incredibly entertaining to fool around with on the train! It only uses a couple layers and low-quality graphics, and there aren't too many sprites; so, it shouldn't be all that trying on resources.

Now, I just need to somehow port the game to android. And I'd also like to be able to use the tilt feature on my android phone to move my champion around.

Questions:How long a process is it?Where can I get started?-or- Is there a comprehensive guide to getting this done?Will there be any lag issues?

The next step: I want to be able to configure my game on my phone. Any pointers?

That's great that you have something that you want to wrap up for distribution. There are a ton of awesome tutorials on the site which you can find here:
